P05-10 Changes in mental health and physical activity patterns before and during the covid-19 pandemic in Swedish adolescents - a longitudinal study

Abstract Background The covid-19 pandemic has had a large impact on the daily lives of adolescents, even in Sweden where the restrictions were relatively mild. The aim of this study was to examine if there had been a change in mental health outcomes and if these changes were related to changes in physical activity patterns before and during the pandemic. Methods In this longitudinal study, data were collected in the autumn 2019 and in follow-up measurements in the spring 2021. Physical activity and sedentary time were measured for seven consecutive days by accelerometry (Actigraph). The mental health outcomes, health-related quality of life (HRQoL) and psychosomatic health were measured with questionnaires (KIDSCREEN-10 and PSP). ANCOVA analyses were applied to estimate the associations between change in physical activity patterns and mental health outcomes. Results In total, 585 boys (45%) and girls (55%), aged 13-14 years (baseline) from 34 schools around Stockholm, were included in the study. Between 2019-2021 there was a decrease in HRQoL (p > 0.001) and increase in psychosomatic problems (p > 0.001) among both boys and girls. There was a significant positive relationship between change in MVPA and change in HRQoL (β = 0.02, CI: 0.00, 0.05). Conclusions The results suggest that the COVID-19 pandemic has impaired the mental health of Swedish adolescents but increased physical activity was related to positive changes in the mental health outcome HRQoL.

Background
The covid-19 pandemic has had a large impact on the daily lives of adolescents, even in Sweden where the restrictions were relatively mild. The aim of this study was to examine if there had been a change in mental health outcomes and if these changes were related to changes in physical activity patterns before and during the pandemic.

Methods
In this longitudinal study, data were collected in the autumn 2019 and in follow-up measurements in the spring 2021. Physical activity and sedentary time were measured for seven consecutive days by accelerometry (Actigraph). The mental health outcomes, health-related quality of life (HRQoL) and psychosomatic health were measured with questionnaires (KIDSCREEN-10 and PSP). ANCOVA analyses were applied to estimate the associations between change in physical activity patterns and mental health outcomes.

Results
In total, 585 boys (45%) and girls (55%), aged 13-14 years (baseline) from 34 schools around Stockholm, were included in the study. Between 2019-2021 there was a decrease in HRQoL (p > 0.001) and increase in psychosomatic problems (p > 0.001) among both boys and girls. There was a significant positive relationship between change in MVPA and change in HRQoL (b = 0.02, CI: 0.00, 0.05).

Conclusions
The results suggest that the COVID-19 pandemic has impaired the mental health of Swedish adolescents but increased physical activity was related to positive changes in the mental health outcome HRQoL.

Background
Physical activity (PA) in Czech children is insufficient. In the last two decades, the prevalence of physical inactivity and excessive time spent in sedentary activities has increased (Gába et al. 2019). The determinants of PA are complex and wideranging: individual, socio-demographic, interpersonal, environmental. Motor skill acquisition in early childhood may be an important prerequisite for child PA participation and engagement in PA later in life (Loprinzi et al. 2012). The aim of this study was to estimate motor competence (MC) level in a Czech school children, identify children with motor impairments and analyze the possible causes.

Methods
The research sample was made from Czech school children (n = 195, 110 girls, and 85 boys) of average age 11.96AE1.96 years. To estimate an MC, we used the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, a complete form. We evaluated total motor composite (TMC) and four subcategories: fine manual control, manual coordination, body coordination, and strength and agility.

Results
Our TMC results correspond to a secular reduction in MC. The results show that the group's MC is in the lower part of the average level (TMC standard score 45.4AE11.7). The overall percentage of children whose TMC is above the 15th percentile is 64.6%. Conversely, 35.4% of children do not meet the criterion in TMC. On average, the weakest performance was recorded in the area of fine manual control (standard score 38.2AE11.6). More indepth analysis showed that the weakest subcomponent of fine manual control was fine motor precision (scale score 9.3AE5.8) and fine motor integration (scale score 10.7AE6.1). Conclusion 24 children (12.3%) had well-below average results (TMC<5th percentile). These children are highly likely to develop a developmental coordination disorder. It is a significantly higher result than in the literature reported around 5 -6% in school-age children. 69 children (35.4%) had below-average result of TMC Abstract citation ID: ckac095.079 P05-12 Objectively measured physical activity, chronic illness and health service utilisation -a latent class analysis of activity behaviours in older adults

Background
Physical activity contributes to the prevention of chronic illness as well as promotion of physical and mental health, but most adults remain inactive. Chronic illness affects mainly middle aged and older adults, and very little objectively measured data on physical activity behaviours and associated health outcomes of this population is published.
